Salar de Uyuni in Bolivia is the world's largest salt flat and the most surreal natural wonder you'll ever find. The 4,086 square mile (10,582 sq. km) expanse of perfectly flat terrain is covered in a thick crust of salt that forms over the seasonal brine of the Altiplano's ancient lakes. The flats offer a picture postcard landscape with no horizon – just an endless, white expanse extending all the way to the Andes mountains, whose snow-capped peaks seem to display almost all hues of the rainbow. Salar de Uyuni is home to pink flamingos, cacti, hot springs, and its own unique cuisine, offering the ultimate Chilean experience. While here, don't miss the chance to visit the old train cemetery from the days of Uyuni's historic railway, featuring broken locomotives and wagons, rusting in the sun.
